It all depends on the weight. I chose the KTM 690 for its low weight (139kg dry, 154kg wet) and ability to cross ploughed fields if necessary whilst still able to undertake long cruising speed liaisons without needing to service it more than every 10,000km.
So the 690R has 40 kg advantage over the BMW F800GS.
I can imagine the KTM 790 engine will weigh more than the 690, it will have a bigger tank, a proper rear subframe, better wind protection. If KTM can do that within 15-20kg it would be in a class of its own, if it adds 30-35kg the 790 will be just another midrange adventure bike.
